.sclaims. (c1. 271-69) The present invention is illustrated as applied to a gas burner giving even heat for cooking and having a gas supply which may be distributed to any particular part of a cooking vessel whether large or small. 'I'he principal object is to provide a valve for such a burner in which the location and distribution of the ame may be changed at will by the use of a single valve and in which the quantity of gas supplied to the burners may l0 be controlled at any selected distributive position of the valve.

To this end, there is provided a burner having a plurality of substantially concentric sections with gas openings so arranged that the heat will be even, each section having a separate gas supply controlled by a distributor valve movable to give different arrangements of ame so that heat may be furnished selectively to any particular part of the cooking vessel in successive zones, so that if cooking is advancing too rapidly at the center,

gas may be shut oii from the central section and turned on where cooking is too slow as at the outer edge of a large frying pan.

A still further object of the invention is to provide a valve for a burner such as described lwhich may be moved to open 'the gas supply passages beginning either at the outer ring-like section or at the central section and proceeding in serial order until all sections are opened, the

valve then being movable to close sections in serial order from either the center or from the outermost section.

Another object is to provide an arrangement in which the alternate sections only may be 85 opened to give a more diiused name.

In the accompanying drawing showing a preferred form of the invention, Figure 1 is a plan view with portions broken away of a plurality of sections connected to a valve casing and valve shown in section on the line I-I of Fig. 2; Fig. 2 is a vertical section on the line II-.II of Fig. 1;, Fig. 3 is a fragmentary horizontal section/as in Fig. l, with the valve turned through :180 from the position of Fig. l; and Fig. 4 is a fragmentary 5 plan' view of the valve.

'I'he gas burner shown in Fig. 1 consists of five sections desig sed as I, 2, 3, 4, and 5, each section comprising "an annular chamber having a supply pipe leading to a gas inlet secured within a valve casing and communicating with a gas outlet passage in the casing controlled by a gas cock.

The supply pipe 6 of outer section I leads directly to gas inlet l; supply pipe 8 of the next section, 2, leads to inlet 9 after passing beneath site the passage 3l.

section I; supply pipe I0 of section 3, passing beneath sections I and 2, leads to inlet II; supply pipe I2 of section 4, passing beneath sections I,

2, and 3, leads to inlet I3; and supply pipe I4 of the innermost section, 5, passing beneath sections 5 I, 2, 3, and 4, leadsto inlet I5. 'The valve casing I6 has a tapered bore I1 from which gas outlet passages I8, I9, 20, 2I, and 22 extend to the gas inlets l, 9, I I, I3, and I5 respectively, the ends of the gas outlet passages within the bore preferably lying in the same horizontal plane and being spaced uniformly from each other. A isapered distributor plug 23, tting with a ground bearing for rotation within the tapered bore I7, is provided with a tapered bore 24 to receive a 15 correspondingly tapered plug 25 which may be held in the plug 23 by a screw 26. The plug 25 has an axial bore 21 which may be closed at its upper end by a closure member 28 upon which a wheel or other handle member 29 isv secured 20 as by a screw 30.

An annular groove 3I is formed around the plug 23 opposite an opening in the casing I6 which receives the nipple 32 connecting the valve casing with the main gas supply pipe 33. From 25 this groove 3l, a bore 35 extends through the wall of the plug to the bore 24. A similar bore 35 is formed in the plug 25 to register with the bore 3Q in one position of the plg 25 and to be moved out of register with the bore when the plug 30 25 is rotated in either direction through a distance equalto the width of the bore 3B.

At the upper e'nd of the borel 2l', a bore 35 leads through the wall of the plug to a passage 3l milled or therwise formed in the plug 23 and 35 having a width at its outer side somewhat greater than the space within which lie the ends of the gas outlet passages 58 t9, 20, 2I, and 22. Diametrcally opposite the bore SI5, the plug 25 has formed, as by milling, a. passage 3B communicat- 4o ing with the axial bore 2l and having a width at its outer side somewhat greater than the space within which lie the inner ends of three passages 33, lll?, and di formed through the plug 23 oppo- As 'a means for rotating 45 the plug 23, a handle d2 is shown as formed with a. sleeve surrounding the upper end ed of the plug 23 and secured thereto by a screw 45.

In the position of parts illustrated in Figs. l.

and 2, gas from the pipe 33 may flow through 50A bores 3d, 35, 2l and 36 to the passage 3l leading to all ve of the'passages' I8, I9, 20, 2I, and 22 radiating outwardly to the inlets l, 9, II, I3, and I5 supplying all five sections of the burner.

If the plug 23 is turned in a clockwise direction, 55

the solid portion BB will move across the passage 22, shutting ofi gas from the central burner section 5 but permitting sections I, 2, 3, and 6 still to remain supplied with gas. Further clockwise rotation will close passage 2| to shut oi gas from section Il, section 5 still remaining closed, but sec'-` tions i, -2, and 3 will still be supplied with gas. Still further clockwise movement will close passage 2|)A without opening passages 2| or '22 but leaving sections and 2 supplied with gas. The

next further clockwise movement will close passage i9, leaving section i only still supplied with gas and further movement will close passage i8 and thus shut oi gas from all ilve sections, the solid portion 36 of the plug being of suillcient length of arc to close all five passages.

Starting again with the valve position shown in Fig. 1 and rotating the plug 23 in a counterclockwise direction, the solid portion'll of the plug 23 will act toclose passage i8 first, shutting oir' gas from section i but leaving sections 2, 3, t, and 5 supplied with gas. Further rotation counterclockwise will close passage i9, then passage 23, then passage 2|, and nally passage 22, shutting oi the gas supply ofthe sections from the outside inward successively toward the center, the solid portion 'i of the plug 23 being of suflcient length of arc to close the ends of all five passages at once.

If the plug 23 is rotated through 180 to the position shown in Fig. 3, the passages 39, 4|?, and Iii will register with passages i3, 20, and 22 respectively, passages i 9 and 2| being closed by the solid portions 48 and 69 of the plug. Sections I, 3, and 5 of the burner will thus be supplied with gas and sections 2 and l will be shut ofi. Rotation of the plug clockwise will close passages I8, 20, and 22 and will open passages i9 and 2| to supply sections 2 and 4 while the other sections are closed. Still further clockwise rotation of the plug will close passages i9 and 2| and open passages I 8 and 20, the solid portion 41 of the plug closing passage 22 as well as passage 2|, leaving only sections I and 3 supplied with gas. The next clockwise movement will close passages I8 and Y 20 and open passage i9 alone to furnish gas only to section 2, and furtherclockwise movement will close passage' `|9 andjopen passage I8 to gas for section only.

Rotation of the plug 23 from the position of Fig. 3 counterclockwise will also first close passages I8, 20, and 22 andthen open passages I9 and 2| to passages 39 and 40, to supplygas to sections 2 and 4, the apparent effect being the same as if the movement had been clockwise as previously described, but further. counterclockwise rotation will open passages 20 and 22, this arrangement supplying gas to the small central burner section 5 and to the burner section 3,

giving a somewhat larger area of flame than with 'the arrangement previously described in which only sections 4 and 5 were open. Additional counterclockwise rotation will close passages 20 and 22 and then open passage 2| to supply gas only to section 4, the solid portion 4S closing passages |8, I9, and 2|), and the solid portion 49 of the plug closing passage 22. The next counterclockwise movement will close passage 2| and open passage 22 for gas to section 5, all other passages to the burner sections being closed.

It will be seen that by this simple rotation of the single valve plug 23, the distribution of the gas supply and hence of the flame may be variedby the selection of the diierent combinations of sections available, and with any distribution selected, the quantity of gas delivered ,may be regulated from a full supply to a complete shutoif by rotation of the plug 25.

For convenience in cleaning, thefburners may be made separable, preferably with an inverted V joint as indicated at 50 in Fig. 2.
